The cool cats at Engadget Japan have published what’s apparently a schematic of the upcoming iPhone 6S, which came from a source in the Chinese supply chain. The schematic shows a handset with only minimal changes from the current iPhone 6 and 6 Plus.

In truth, the changes to the handset’s thickness appear to be imperceptible, as the thickness marked on the schematic is 7.1mm – just 0.2mm thicker than the iPhone 6, and the exact same thickness as the iPhone Plus.

With these relatively unchanged numbers, it seems possible that your current iPhone 6 and 6 Plus case will fit the new model.
